Abstract

An abrasive disc which may be attached to a holder having a suction device associated therewith. The disc includes a body of soft, resilient material and abrasive layers on both sides. Apertures, openings, and orifices in the abrasive layers and in the edge of the body allow air and particles to be drawn into internal passages in the body of the disc and flow out of the body to the suction device in the holder. The apertures also facilitate attachment of the abrasive disc to the holder.
